Hi,
I have a problem with quoting in one of my functions:
now TIMESTAMP := ''now'';
FOR myRec IN SELECT * FROM myTable WHERE job_end + ''360 Min'' > now LOOP
I want to replace the 360 with the contents of a passed value
but for some reason I can't quote it. ... job_end + ''$1 Min'' does not
work.
Could anyone help me out here ?
On the subject:
The whole quoting in PLPGSQL seems to create many people a headache...
is there any plan to make it a bit more user friendly?
Thanks
Alx

Hi Alex,
If you want to achieve say '360 min' as the string you will have use
concatenation:
FOR myRec IN SELECT * FROM myTable WHERE job_end + ($1::text || '' Min'') >
now LOOP
The syntax is SQL rather than PHP-like.

Your main question has been answered, but you might want now() rather than
''now''. Off the top of my head, I think the ''now'' might get compiled as a
value on the first run and stay at that value.

Hi Jason,
thanks, for the reply. Tried that one but still getting an error

TIP 7: don't forget to increase your free space map settings
Hi Richard,
as for the timestamp, both ways work fine, but the other problem still
exists. using a
''60 Min'' works just fine, but WHERE job_end + ($1::text || '' Min'' ) now
does not. job_end is timestamp without tz

Hello
Don't use now or current_time, use
LOCALTIMESTAMP
CURRENT_TIME and CURRENT_TIMESTAMP deliver values with time zone;
LOCALTIME and LOCALTIMESTAMP deliver values without time zone.

You probably want a cast:
+ ($1::text || '' min'')::interval

Yes, there's a new cool quoting method that will make it much headache
unfriendly. It will probably be there in 7.5 (not 7.4, sorry).

You probably need an explicit cast from text to interval. An untyped
(unknown) string gets handled differently than one of type text.

This is pretty much the hard way, though. A better idea is to use the
number-times-interval operator:
timestampvalue + $1 * '1 min'::interval;
Easier to write and faster.
